Things to Consider when Getting a New Diesel Injector Hose
Fuel, air, and well-timed spark are what the engine needs to dish out power and keep the vehicle running. If fuel delivery is messed up due to a busted diesel injector hose, that tiger under the hood can easily turn into a scared-y cat. The hose may develop internal cracks due to electrochemical degradation and can turn soft and mushy. It may also form a hardened glassy surface due to heat damage and may get weak with collapsed portions or nicks and bulges in them. If you're searching for a new diesel injector hose, let us help you find the right one.
Getting an individual hose vs. buying a kit
When replacing a broken diesel injector hose, you have the option of just buying a replacement hose or getting a complete kit. Before you make up your mind, you have to inspect the fuel injector hose first. It usually takes a close look at the fuel injector hose to find out if this needs to be replaced and if there are other things that should also be fixed such as the fittings or clamps. Check if the hose is firm and pliable by squeezing it, especially near the connectors. It shouldn't be soft and floppy nor hard or stiff. If there's swelling, kinking, bending, or cracking, this means that the weak or worn-out hose must be replaced right away. To find out if all you need is just a new hose and not a kit, also inspect the clamps, fittings, and other connections. There might be a trace of leak or moisture on or around the clamps or connector. This can be brought about by insufficient clamp torque or a deteriorated hose. If the clamps that hold the hose in place are corroded or already worn, you must get a kit. A weak clamp can cause eventual hose damage and potential leaks. Aside from a fuel injector return line, a diesel injector kit usually includes plastic fittings, clamps, and O-rings. These pieces allow for quick and easy installation.
Crucial specs and features to consider
Hoses come in different sizes and lengths, so before you place an order, you have to make sure that the replacement product comes in the right dimensions. Some of them are sold by foot or by shorter sections. The inner diameter of the hoses is measured by inches (5/16 or 3/8 inch, for instance). Make sure that the diesel injector hose matches the fittings or connectors. To find the appropriate replacement, shop by make and model. Also indicate the model year to get a replacement part that perfectly fits the engine specifications. Other than the size, also check other item specifics such as the material, whether it's made of nylon (which comes as a gas-resistant tubing) or neoprene (with an outer steel braiding). A durable hose can better withstand EDC or electrochemical degradation and can resist deterioration due to heat. Take time to check if the kit is remanufactured or the hose is sold as brand new.
